Portchannel going down when remove/add from vlan member ports

dev-aviz commented 4 years ago

Description Portchannel going down when remove/add from vlan member ports

Describe the results you received: Portchannel going down when remove/add from vlan member ports

Describe the results you expected: Portchannel shouldn't go down when remove/add from vlan member ports

Steps to reproduce the issue:

Topology:

3 IXIA ports ---- Mellanox Leaf1 ----- pch1 --------- Mellanox Leaf2 -- 1 IXIA port
